@TestTargets是什么 JAVA单元测试的问题，JUNIT，等你不关机


问个低级的问题：下面这段是什么意思呀？ @TestTargets是什么意思呀？
@TestTargets({
@TestTargetNew(
level = TestLevel.COMPLETE,
notes = "Test vibrate",
method = "vibrate",
args = {long[].class, int.class}
),
@TestTargetNew(
level = TestLevel.COMPLETE,
notes = "Test vibrate",
method = "vibrate",
args = {long.class}
)
})
